4. Agenda: Intro to containers and Docker
Oracle DB running in the Oracle Cloud’s Container Services
Oracle Database running on your local server/laptop
Demo Oracle DB – in Docker

5. Alternatives to docker
Open Container Initiative,
Kubernetes,
CoreOS - rkt,
Apache Mesos and Mesosphere,
Canonical - LXD

6. Docker is the company driving the container movement

7. docker
Solomon Hykes started Docker in France as an internal project within dotCloud
An evolution of dotCloud's proprietary technology
Docker was released as open source in March 2013

8. docker Lightweight virtualization = Speed + Space Easy updating
Test against the same image as production.
Automate and speed up your build process.
Distribute and deploy scalable services.

9. docker Increase setup, configuration complexity
Containers share the same kernel
Elevated OS privileges may be needed.
Containers not made for GUI systems

10. docker
Enterprise Edition
Community Edition

12. Docker behind the scenes

13. VM
Docker container vs VM

14. Docker service The Docker software as a service has three components:
The Docker daemon – “dockerd”
Objects
Docker Container
Docker Image
Docker Services
Registries – repository for Docker images

15. Docker orchestration Tools
Docker Swarm
Docker Stack
Docker Compose

16. Docker image
Permanently stored image of the environment that Docker uses to create a container

17. Docker container
By default all files created inside a container are stored on a writable container layer

18. Image vs container

19. Docker storage
Volumes are stored in a part of the host filesystem which is managed by Docker. Non-Docker processes should not modify this part of the filesystem. Volumes are the best way to persist data in Docker.
Bind mounts may be stored anywhere on the host system. They may even be important system files or directories. Non-Docker processes on the Docker host or a Docker container can modify them at any time.
tmpfs mounts are stored in the host system’s memory only, and are never written to the host system’s filesystem.

20. docker stats

22. DOCKER COMMANDS docker build docker port docker commit docker ps
docker cp
docker create
docker exec
docker export
docker import
docker history
docker network
docker stop
docker stats
docker system
docker port
docker ps
docker pull
docker push
docker rename
docker rm
docker rmi
docker run
docker service
docker stack
docker start

23. Docker container resources
Understand the risks of running out of memory
It is important not to allow a running container to consume too much of the host machine’s memory.
Configure the default CFS scheduler
By default, each container’s access to the host machine’s CPU cycles is unlimited.
You can set various constraints to limit a given container’s access to the host machine’s CPU cycles.

42. Oracle Container services
to connect to database using your docker (for example if you don’t have an installation of oracle client on your laptop) you can use oracle’s docker instant client
docker run -ti --rm store/oracle/database-instantclient: sqlplus as sysdba"

43. Oracle Container services
to log onto the host:
ssh -i oowdemo_rsa xxx xxx xxx

44. Oracle Container services
~]# docker exec -it 0.OracleDB12.2.OracleDB bash -c "source /home/oracle/.bashrc; sqlplus /nolog"
